Read about this from the Internet and the more I read about it, the more I worry. Therefore, I think its good to share with you all.
Best Article I came across on this topic is from PC World –
Understand that Microsoft just release their monthly windows updates but on the next day, someone found a bug in Win7 and Win2008R2 – read more from this site
So, to be on the safe side, until Microsoft completes its investigation of the issue and releases a patch, my advise is to be avoid suspicious or malicious links on web pages.
